Same thing you guys do... the slaughter of American Indians for their land and mass murder of an entire culture.
On the positive side.... we celebrate our moms's groovy stuffing and juicy turkey.... the awesome canned cranberry sauce, gravy.... carrots, cauliflower, cabbage, mint sauce, butter, mashed potatoes, wine, peas.... etc... then the christmas pudding and custard for desert..... and if you can handle it... pumpkin pie with whippped cream and a cup of tea.
mmmmm......... then a few hours later after a nice sleep, some jam tarts and eggnog.
